Twenty-five samples of Bulimulus species are studied, partly from localities within their known distribution range, partly based on interceptions where the material originates from localities where the species seem to be recently introduced and non-native. Molecular study of cytochrome oxidase 1 (CO1) reveals the origin of some of these introductions, but is less conclusive for others. Four different methods for species delimitation were applied, which did not result in unambiguous species hypotheses. For a rapid identification of morphologically indistinct species, a more comprehensive database of sequences is needed.
对25个泡螺属物种的样本进行了研究,部分样本来自其已知分布范围内的地点,部分样本基于截获物,这些材料来自该物种似乎是最近引入的非原生地点。细胞色素氧化酶1(CO1)的分子研究揭示了其中一些引入的来源,但对其他一些引入的来源结论性较差。应用了四种不同的物种界定方法,但并未得出明确的物种假说。为了快速识别形态上难以区分的物种,需要一个更全面的序列数据库。
